A Mapperley couple who had a "narrow escape" after Hurricane Irma tore through the Caribbean have launched a fundraising campaign to help the thousands of people on the devastated island.

Sam Stoffel, owner of Profit Accumulator - a matched betting company which says it can help punters win money - made a dramatic escape from Necker Island with his fiancée Emma Lednor, also 27, just before the deadly storm hit on Tuesday (September 5).

The category five storm has blighted the United States and tore across the Caribbean with life-threatening wind and rain.
